WASHINGTON, USA: LG Electronics highlighted the flexibility and power of digital television (DTV) during an "on the go" demonstration of ATSC Mobile DTV. The new standard, just adopted Thursday night by the Advanced Television Systems Committee (ATSC), is already on the air -- showing how TV stations will entice viewers with new options for over-the-air broadcasting to mobile and handheld receivers.
Co-developer of the technology at the heart of the ATSC Mobile DTV standard, LG Electronics applauded the rapid adoption of the flexible new standard, which promises to expand the reach of digital television to a new generation of viewers. To support the commercial launch of ATSC Mobile DTV receivers, mass production of the LG2160A semiconductor chip that will be used by LG and other manufacturers is underway.
Commemorating the new ATSC Mobile DTV standard here today, prototype LG products, including mobile handsets and a personal DTV equipped with reception capability for mobile DTV broadcasts, were taken on a drive throughout the city streets and highways of the nation's capital, showcasing the robust reception characteristics of the new technology.
Mobile prototypes utilized today included both GSM and CDMA handset models as well as a combination personal digital TV receiver and portable DVD player planned for introduction in 2010 that utilizes the new ATSC Mobile DTV chip from LG. The company is also working with automotive electronics and computer makers to incorporate mobile DTV capability into their products.
Seven Washington-area broadcasters are now transmitting Mobile DTV signals, which are sent in the same spectrum used to transmit crystal-clear high-definition and other digital TV programming.
The ATSC Mobile DTV standard allows broadcasters to use a portion of the existing 19.3 Megabit-per-second DTV channel capacity to transmit data with extremely robust characteristics suitable for mobile, pedestrian and handheld applications. The mobile DTV signal is compatible with 8-VSB DTV, which was also developed by LG's U.S. research and development lab, Zenith.
Featuring an automatic power saving mode to maximize battery life for DTV viewing "on the go," the new LG reception chip provides mobile/handheld demodulating and equalization functions, and outputs IP packet streams to enable audio/video decoding in the receivers compatible with the new ATSC Mobile DTV standard.
